APPLIGATION FILED JULY 9,1903.

States Patented March 7, i905.

SPECIFICATION forming part of Letters Patent No. 784,215, dated lllarch 7, 1905.

Application iied Jnly`9, 1903. Serial No. 164.773.

Be it known that I, .Levies E. HUMPIIREY, a citizen of the United States, residing at Aberdeen, in the county of Brown and State of South Dakota, have invented certain new and useful .Improvements in Dinner-Fails; and i do hereby declare the 'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to so-called self-heat ing dinner-pails, or dinner-pails having' heating attachments, and is cspeciall y intended for improvement on self-heating dinner-pails of the character disclosed in the claims in Letters Patent of the United States No. 646,185, issued to Harvey L. and Charles Marlett, of date March 27, 1900.

The invention consists of the novel construction and combinations of parts hereinafter described, and delined in the claim.

lhc invention is illustrated in the accompanying drawings, wherein like characters indicate like parts through the said Views.

Figure l is a View in central elevation showing adinner-pail constructed and equipped in accordance with my invention, some parts of the same being broken away and some being' sectioned; and Fig. 2 is a horizontal section taken on the line X2 X2 of Fig. l.

ln this preferred construction of a pail the body thereof is of rectangular form and is provided with a false bottom Q, between which andthe bottom proper of the body l is formed a horizontally-extended combustion-chainber r3. At one end the combustion-chamber 3 is open, but is adapted to be closed by a sliding door t, mounted in suitable guides 5 on one end of the pail.

rlhe numeral 6 indicates a lamp, such as an alcohol-lamp, which is loosely placed within the comlnistion-chamber 3 as far as possible from the open end thereof. Above the space thus occupied by the lamp 6 the false bottom 2 is cut away, as shown at 7. The main compartment of the body l-that is, that portion above the false bottom Qis iilled by a removable open-ended box 8 and by a removable coffee-can 9, which parts 8 and 9 are, as shown, both rectangular.

9 rests on the false bottom 2 with the greater portion of its own bottom directly exposed to the 'llames from the lamp (i through the opening of the said false bottom. A draftiiue 10 secured at its lower end to the severai portions of the bottom of the can t) and rises vertic-l lly therethrough, with its` upper end projecting above the top of said can. The upper end of the can S) is adapted to be closed by a removable cover i l, which is provided with a simple perforation which quite loosely lits around the upper end ofA the flue 10.

The pail-body 1 is provided with a removable cover 12, which is provided with a threaded sleeve 13, which when the cover l2 is placed in working position loosely telescopes over the projecting upper end ol the flue '10. The open upper end of this sleeve 13 is adapted to be closed by a threaded cap 1li. The pail-body '1, as shown, is provided with an ordinary bail 15, and the cover l2 is shown as provided with an ordinary tin cup 1G and cupholding sleeve 17.

Numeral 18 indicates a sheet of asbestos which is placed between the false bottom 2 and the bottom of the box 8 to prevent excessive heating1 of the solid articles of food which would usually be placed in the said box.

When the collee or other liquid contained within the can S) is to be warmed, the lamp 6 is of course lighted, and to give a suflicient supply ol air to" support combustion within the chamber the door 4t m ust of con rse be open more or less. The hot Iiames strike the bottom of the can 9 and then pass up through the iiue l() and rapidly heat the liquid contained in said can. The pail-cover l2 maybe left in position on the body l while thelamp is burning; but the cap 14: must of course be removed at such time. AIn `fact, by placingl the cap la on the neck 'lthe lamp may be snuti'ed out by cutting oli the draft through the flue 10.

W ith the tlue formed as partof the removable ean 9 both of the parts may be removed togther, and thus easily cleaned. To obtain the greatest heating' efiicieney, the flue must be passed centrally through the can, and for The removable coffee-can 1 convenience in usel the said can should of lOO course be removable from the body of the pail. These conditions are all met in my improved pail above described.

That I claim, and desire to secure by Letters Patent of the United States, is as follows:

In a self-heating dinner-pail, the Combination with the body 1 having the false bottom Q perforated at 7 and formed below said false bottom with the combustion-chamber 3 open at one end, of the lamp 6 insertible into said Combustion-chamber below said perforation 7, the can 9 resting on said false bottom over said perforation 7 and provided with the'flue In testimony whereof l aiiix mysignatnre in 2O presence of two witnesses.
